Bowen disease was first described in the medical literature by a physician named JT Bowen in 1912. Bowen disease is also known as squamous cell carcinoma in situ, and is generally considered an early, noninvasive form of intraepidermal squamous cell carcinoma.esions are usually not painful or may not be associated with any symptoms (asymptomatic). In most cases, treatment is highly successful. Bowen disease is considered a pre-cancerous condition, although the risk of developing skin cancer is less than 10 percent. The disorder usually affects older adults.
Polymyalgia rheumatica (PMR) is an inflammatory disorder typically seen in older adults that causes widespread aching, stiffness and flu-like symptoms.It is more common in women than men, and is seen more often in Caucasians than any other race.MR may also occur with another serious condition called giant cell arteritis (also known as temporal arteritis), which can be dangerous. Headaches -- particularly on the side of the head -- scalp tenderness, vision changes or jaw pain when eating can be signs of this condition. PMR can be hard to diagnose.
